CORN-HARVESTER.

Specification of Letters Patent. Patgqentgdl July 1? 1917.

Application filed May 7, 1914. Serial No. 836,852.

To all whom it may concern:

Be it known that l, BERT R. BENJAMIN, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have'invented certain new and useful Improvements in Corn-Harvesters, of which the following is a full, clear, and eXact specification.

My invention relates to corn harvesters.

It has heretofore been proposed to provide corn harvesters with bundle elevators adapted to receive the bundles discharged from the harvester and carry them away to a wagon or other receptacle following the binder in the field. Difliculty has, however, been ex perienced with such elevators due to the fact that the conveyers thereon do not grip the bundles positively and feed them out promptly, an extra man being often required to follow the machine and, when the conveyer combs through the stalks forming the bundle, start the bundle outward by shifting it into engagement with the conveyor.

My invention has for its object to improve the construction of these conveyers in such a manner that the conveyer will grip the bundle discharged from the harvester as soon as it is discharged by the latter, the bundles being thereby carried away with increased facility and celerity, and without any combing action of the conveyer or necessity for the starting of the bundle by the additional operator. I attain these objects by providing improved bundle elevating and conveying mechanism so constructed that the moving element thereof engages the head of the bundle directly and is brought into more immediate contact therewith throughout a substantial length of the same in such a manner as to increase its bundle gripping capacity and thereby increase its efliciency and accelerate the delivery of the bundle.

In order that my invention may be fully and clearly disclosed, I have illustrated in the accompanying drawing one embodiment which the same may assume in practice. In this drawing my invention is illustrated in connection with a corn binder and conveyor of standard construction, a rear elevation of the same, partially in section, being shown.

The binder illustrated comprises a wheeled frame 1 carrying the usual binding mechan m and discha g g mechanism 3 operatively connected to the binder main wheel 4: in a well-known manner and adapted to bind the corn into bundles and eject the same while in upright position rearwardly and stubblewardly between curved spring guides 5. As a bundle passes out from between these guides 5 its butt passes oil from the butt support 6 on the binder and it falls stubblewardly about its butt as a pivot onto a stubblewardly and upwardly disposed endless conveyer 7 having a series of teeth or other suitable bundle gripping members 8 carried thereon and movable longitudinally of an elevator casing 9, the conveyer"? being operatively connected to the binder mechanism through suitable power connections 10, while the casing 9 is pivoted to the main frame at 11 at a point beneath the butt support 6.

In my improved construction the conveyor casing is provided with a peaked or arched bottom 12 near its lower end, which reaches its maximum height at a point substantially opposite the lower end of the bundles as they fall on the conveyor after passing out between the arms 5, and from that point, slopes away gradually toward the stubbleward end of the conveyer. By this construction it is to be noted that when a bundle falls in prostrate position upon the elevator, due to the arched bottom disposed beneath the moving conveyer, the lat ter, since it must move over the peak on the bottom of the elevator, is brought into direct contact with the entire upper end of the bundle so that it may grip the bundle at points along the length of the latter between its head and its center in such a manner as to positively carry it outward; in other words, the conveying mechanism is guided through such a path that it conforms sub stantially to the shape of the bundle as the latter is deposited upon the elevator, and its gripping members are thereby brought into direct contact with the bundle so that a more positive gripping action is obtained which results in the bundle being fed forward positively and promptly upon its delivery to the elevator without any combing action on the part of the conveyer teeth or any tendency to break the ears from the stalks.

While I have in this application described one form which my invention may assume in practice, it is, of course, -,t0 .be understood that the form shown herein is designed or purposes of illustration and that the inventienm y beeiribediediin et er terms without partirgifrromi-ts spirit What I claim as my invention, and desire to secure by Letters Patent, is:

1. In combination, a binder, having discharge mechanism and a bundle elevator operatively connected to thebinder ior receiving bundles therefrom, said elevator haveng ge zth smallest pa t v ef a bu d dep sited thereon when discharged from the binder.

In combination, a binder, and a bundle ele ater eperatively connected thereto for iiE-fi fiwl g :bundles therefrom, said elevator raised portion to insure a secure gripping hereef hysaid g pping m mber- .In testimehy hereo I iaflix any ign ture, in the presenoe of two witnesses.
